introduction | 4-hydroxycyclohexanone ethylene glycol acetal is also called 1, 4-dioxa spiro [4.5] decan-8-ol, which can be used as an intermediate in organic synthesis. It can be obtained by the reduction of 4-dioxa [4,5] decan-8-one. |
prepare | 250ml three-mouth bottle with thermometer plus 1,4-dioxacyclo [4.5] decane -8-one (10g,64.03mmol,1eq.), MeOH(80ml), stir, a small amount of insoluble, add sodium borohydride (0.61 g 0.6g,3.2mol) twice in ice water bath, 0.5eq.). After addition, the ice was removed and stirred in water bath. TLC(DCM:MeOH = 100: 1,2, 4-dinitrophenylhydrazine color development) showed complete reaction after 0.5h. Add water (40ml), evaporate methanol under reduced pressure, and extract ethyl acetate (50 50 25 25ml). The organic phases were combined, anhydrous magnesium sulfate was dried, filtered by suction, and the filtrate was evaporated under reduced pressure to obtain 10.02g of colorless liquid with 98.9% yield. |
